How the estimate works
The applicable OPM table controls both your rate and the overtime threshold.
- 01
Confirm coverage
Use the ordinary Title 5 path only for an FLSA-exempt GS employee.
- 02
Resolve the pay cell
The tool reads the exact 2026 OPM basic hourly rate and same-table GS-10 step 1.
- 03
Apply eligible hours
Overtime is full pay; night, Sunday, and holiday entries are incremental premiums.
Ordinary GS premium-pay rules
Percentages use the applicable basic hourly rate, including locality or a qualifying special-rate floor.
| Pay lane | Rate | Calculator treatment |
|---|---|---|
| Title 5 overtime | Variable | 1.5× employee rate below the GS-10 step 1 threshold; otherwise the greater statutory rate |
| GS night pay | +10% | Incremental premium for eligible regularly scheduled night work |
| Sunday premium | +25% | Incremental premium for eligible nonovertime Sunday work |
| Holiday premium | +100% | Incremental premium for eligible nonovertime holiday work |

Federal overtime questions
How is Title 5 overtime pay calculated?
For an FLSA-exempt employee whose hourly basic rate is at or below applicable GS-10 step 1, the overtime rate is one and one-half times the employee rate. Above that threshold, the rate is the greater of the employee's hourly rate or one and one-half times applicable GS-10 step 1.
Why might a higher-grade employee receive less than time and a half?
Title 5 limits the ordinary overtime formula once the employee's basic hourly rate exceeds applicable GS-10 step 1. The result can be the employee's straight hourly rate when that is greater than one and one-half times the threshold rate.
Can night, Sunday, and holiday premiums apply to the same hours?
OPM says night pay may be paid with overtime, Sunday, or holiday pay when each entitlement's conditions are met. Sunday and holiday premiums use the basic rate and are calculated separately, not compounded on one another. Agency records control which hours qualify.
Does this calculator work for FLSA-nonexempt employees?
No. FLSA overtime uses a regular-rate calculation that can include additional remuneration and a separate statutory comparison. The tool stops without dollars and links to OPM's FLSA computation guidance.
Does the estimate enforce federal premium-pay caps?
No. Title 5 biweekly and annual limitations depend on other pay and sometimes agency emergency or mission-critical determinations. Confirm the payable amount with agency payroll.
Who decides whether the entered hours are eligible?
The employing agency does. Official orders, work schedules, time and attendance records, FLSA status, and the controlling pay authority determine whether overtime or a premium is payable.
